[Grok-dev] grok_release_url parameter branch

[Leonardo Rochael Almeida]

Hi,

I've made a small step in the direction of having grokproject work off
of a tarball instead of requiring Internet for it's operation. It's
sitting on a branch at:
svn://svn.zope.org/repos/main/grokproject/branches/rochael-alternate-grok_release_url

It just implements an optional paster variable that, if provided,
makes grokproject assume it as the location of the grok
release/version information (and eggbasket) files instead of the
canonical location. Tests were also added (and some previous broken
tests fixed).

Should I merge it to trunk?
